Methods for recognizing gestures made by a conductive object on a touch-sensor pad and for cursor motion are disclosed. Tapping, drags, pushes, extended drags and variable drags gestures are recognized by analyzing the position, pressure, and movement of the conductive object on the sensor pad during the time of a suspected gesture, and signals are sent to a host indicating the occurrence of these gestures. Signals indicating the position of a conductive object and distinguishing between the peripheral portion and an inner portion of the touch-sensor pad are also sent to the host.

[ What is claimed is:] [1.] A method for recognizing an extended drag gesture made on a touch-sensor pad in a touch-sensing system providing X and Y position information to a host, including the steps of:detecting a first presence of a conductive object on the touch-sensor pad of a first duration between a start and a finish of said first presence;comparing said first duration with a first reference amount of time;initiating a gesture signal to the host indicating the occurrence of a gesture if said first duration is less than said first reference amount of time;detecting a second presence of a conductive object on the touch-sensor pad of a second duration between a start and a finish of said second presence;comparing a first elapsed time between said finish of said first presence and said start of said second presence with a second reference amount of time;maintaining said gesture signal and repeatedly sending X and Y position information to said host for said second duration if said first elapsed time is less than said second reference amount of time;detecting a third presence of a conductive object on the touch-sensor pad of a third duration between a start and a finish of said third presence;comparing a second elapsed time between said finish of said second presence and said start of said third presence with a third reference amount of time; andmaintaining said gesture signal and repeatedly sending X and Y position information to said host for said second elapsed time and said third duration if said second elapsed time is less than said third reference amount of time.
